A dump body pivot pin, suspension node, and rear frame connection comprises a dump body pivot pin boss, a rear suspension connection boss, outer and inner upper rear frame tube connection bosses, outer and inner lower rear frame tube connection bosses, upper and lower beams, a beam connection web, and a support tube connection boss. The dump pivot pin boss has a pivot bore, a pin bore center axis, and inner and outer flat surfaces. The rear suspension connection boss includes a suspension connection center axis and inner and outer flat surfaces. The upper beam connects the outer and inner upper rear frame tube connection bosses to the dump body pivot pin boss. The lower beam connects the outer lower rear frame connection boss to the rear suspension connection boss and the dump body pivot pin boss and the inner lower rear frame tube connection boss to the dump body pivot pin boss.

A vehicle has at least two axles, each having at least one wheel for lifting, transporting, and lowering load carriers. A first axle is mounted in a chassis. Lifting elements are provided for lifting and lowering the load carriers. The distance of the second axle relative to the first axle can be changed in the horizontal longitudinal vehicle direction, and the lifting elements are lifted or lowered by a change in the distance of the second axle from the first axle. The at least one wheel of the first axle can be driven by a drive motor that is arranged on the chassis, and at least one lifting element is displaced horizontally inward or outward by the change in the distance of the second axle from the first axle in the transverse vehicle direction.

A loading and transport system is disclosed that engages with a transporting vehicle such as a hauler or semi-truck. The system includes a plurality of transporting components including platforms or compartments that are accessible independently for efficiently loading and unloading objects including vehicles or freight boxes.

An apparatus is mountable on a truck or trailer bed for lifting industrial or agricultural spools for transport. The apparatus includes a pair of vertically pivotable lifting members, each one of the pair of lifting members having a distal end. A pair of lifting pins are mounted to a distal end of a corresponding lifting member. A drive system is operably connected to the pair of vertically pivotable lifting members whereby the pair of lifting pins engage a hole of a spool and the spool is lifted with the vertically pivotable lifting members by a drive system.

Embodiments of the present invention include a method and system for controlling the flow rate of materials into and out of the blender. The system includes the control and management of an on-site storage system for each component of a mixture, regulating the delivery rate of a blend mixture into a blender hopper, regulating the exit rate of the blended mixture from the blender hopper, and coordinating the flow of materials into and out of the blender.

A reel handler system includes a first arm and a second arm. A first member is coupled to the first arm and a second member is coupled to the second arm. A sleeve has the members movably positioned therein. A first bracket has a first link coupled to the first arm and a second link coupled to the sleeve. The links are pivotable relative to one another. A second bracket has a third link coupled to the second arm and a fourth link coupled to the sleeve. The third and fourth links are pivotable relative to one another. The brackets are movable to increase and decrease a distance between the arms from a first configuration in which the first and third links are spaced a first distance apart from the sleeve and a second configuration in which the first and third links are spaced a second distance apart from the sleeve.

A manipulator apparatus for manipulating an article is disclosed. The apparatus includes an arm including a connecting end and a working end, an arm actuator coupled with the connecting end by an arm linkage, a lift actuator coupled with the connecting end, an end effector coupled with the working end by a rotatable connection, the end effector having an engagement orientation relative to the working end, and at least one cable coupled between the connecting end of the arm and the rotatable connection. The arm actuator is operable to cause the arm linkage to move the working end until the end effector engages an article in the engagement orientation; the lift actuator is operable to cause the connecting end to lift the working end, the end effector, and the article; and the cable is coupled to transmit movement of the connecting end to the rotatable connection to maintain the engagement orientation of the end effector.

Embodiments of the present invention include a method and system for blending multi-component granular compositions such as proppant used in hydraulic fracturing in well drilling. The system includes the control and management of an on-site storage system for each of the components, regulating the delivery of specified quantities of each component to a well site, and coordinating the flow of materials into and out of the blender.
